Assessing the Relationship Between Institutional Size and Student Outcomes in SUNY Community Colleges

This study examines whether economies of scale in staffing translate into greater student success per staff member across 28 SUNY community colleges. Using IPEDS data from 2021–2024, three productivity metrics—Enrollment Capital Efficiency (ECE), Retention Efficiency (RE), and Graduation Efficiency (GE)—were analyzed using ANOVA, scaling regressions, and Most Productive System Size (MPSS) breakpoints. Larger colleges achieved higher ECE and RE, while GE did not differ significantly by size. Positive but sublinear scaling indicated efficiency gains with size without proportional input growth. MPSS results showed that RE breakpoints increased with institutional size, suggesting greater staffing leverage in larger colleges, whereas GE exhibited diminishing returns at higher ECE levels among large colleges. These findings provide replicable metrics and a benchmarking framework for evaluating staffing efficiency, institutional scale, and student outcomes in community college systems.
